On the Deconstruction of Time

In this note we discuss the possibility to get a time rather than space in the scenario of (de)construction of new dimension. 1. Recently it was suggested in refs. [1, 2] that a four-dimensional gauge theory with a large gauge symmetry behaves in the infrared region in a manner which is very similar to a five-dimensional gauge theory with a smaller gauge group. This leads to an idea of (De)construction of extra dimensions, i.e that extra dimensions do not exist at fundamental level and emerge dynamically in the infrared limit. The basic idea of (De)construction is the following [1, 2]. One starts from a theory with a chain of gauge symmetries G1 ×G2 × ...×GN where all groups Gi are identical, i.e. we have
